This invention relates to waste operating mechanisms and has-for its purpose to provide a mechanism that is not dependent upon friction or balancing device and yet is posiin either ope-n or closed position.

In accordance with this invention, a rigid member is employed ,to actuate the waste plug andmeans are associated therewith to 1Q, positively actuate the member and to lock the same particularly in open position in such a manner that the waste plug cannot beaccidentally or inadvertently closed. In the preferred form the member actuating mecha- H nism takes the form of an offset or crank-like arm cooperative with'a hooked end upon the member. V

, A better understanding will be had of this invention from a consideration of the s following detailed description given in connection with the drawings, in which:

Fig. 1 is a vertical section through the center of a waste operating mechanism and including a portion of a receptacle such as a lavatory;

Fig. 2 is a fragmentary section on line 2-2 but with the handle in vertical position illustrating the operating mechanism in partially opened position.

Referring particularly to the drawings, it will be seen that for purposes of illustration this invention has been shown as applied directly to a portion of a lavatory 1, although it may be secured to a fixture orany other convenient member. The lavatory is provided with the usual waste 2 adapted to be closed by a waste plug 3. The waste plug 3 is of the type adapted to fall by its own weight into closing posit-ion and is formed with an integral sleeve-like guiding portion 4 having a grooved end 6. V V

The plug is operated by mechanism comprising this invention and is composed of a cup-like body member 8 having a base flange 9 suitable to be secured to any suitable fitting or fixture such as the top of a lavatory, by a locking sleeve and rod guide 10. The guide member is formed with out-turned or projecting fingers 11 to engagea complementary inturned flange 12 of the body and also with internally as at less than from the handle.

1930. Serial No. 4 7,710;

the, lower end thereof threaded exterior-ly as at, 13 to receive a-locking nut 14.

Slidingly mounted withinthe interiorbore of the guide 9 is a hooked rodlfi formed upon its. upper end with 'a hook 17 and threadedy adjusting stud 19. The lower end'of the stud 19 engages the, upper end of a rigid, fOr ked lever 21. The lower end of the lever 21 is forked as at 22 to freelyengage the groovedeo end 6 oft-he waste plug. c 1

The leveris actuated in a substantially ver tical direction by means of a crank-pin 23 jour a led in slots 2 fo me n th pperend of the body. The crank pin 23 is formed; w th a. center oilset or cran po tio 25 hich engages the hooked end ofthe hoo rod-v A handle 26 of substantial mass and having urcated arms w c pass around the b dy, is pinned to the outer ends-of crank pin 23 n; order to rotate the latter. A dome-like cap 28is threaded to the upper end of the bodyS and. serves to ino oso the body and to hold th I crank pin within its bearing slots.

I As can be seen f1 om Fig. 1, thecrank in; and handle are arranged so that the ofi set portion 25 will be in lower vertical position with the plug 3 in its lower or closed position.

' and with the handle in horizontal position.

The adjusting rod 19 will permit adjustments toproduce this relation. It follows therefore thatshould the handle 26 be rotatedover and to the other side of the housing, the ofiset portion 25 will first beraised into a horizontal position as shown in Fig. 2, then to a sub-. stantially vertical position directly opposite to that position shown in Fig. 1 and will be held in this upper vertical position by the weight of the handle 26which willthfl be in a horizontal position diametrically opposite to that shown in Fig. 1. It isto be noticed that the crank is at an angle slightly Accordingly when the handle is in horizontal open position the. crank will have moved slightly past top vertical position. The weighti'of the waste plug when in open position will also tend to lock the handle and latch in open position and prevent accidental closing of the plug.

18 toreceive one end of an r It follows from the above that there is provided a waste operating mechanism which is positive in its action, which is self-locking particularly in its open position and which does not depend upon friction or balancing devices to retain it in position.

It is obvious that changes may be made in the details of the construction without cleparti-ng from the spirit and scope of the invention as defined in the claims appended hereto.

We claim:

1. In a waste operating mechanism, a body, a rod having a hooked end projecting into said body, a crank pin engaging said hooked end and arranged to positively raise and lower said rod, and means for actuating said crank pin.

2. In a waste operating mechanism, a body, a separable guide secured to said body, a rod slidingly mounted in said guide, said rod having a hooked end projecting into said body, a crank pin within said body engaging said hooked end and arranged to positively raise and lower said rod, and means for actuating said crank pin and maintain ing the same in either of two positions.

3. In a waste operating mechanism, a body, a guide member secured to said body, a hooked rod slidably mounted within said guide member and projecting into said body, a crank pin journalled in the side walls of said body and engaging said rod to positively raise and lower the same substantially vertically, and a handle secured to said crank pin.

4. In a waste operating mechanism, a

body, a guide member secured to said body, a

hooked rod slidably mounted within said guide member and projecting into said body, a crank pin journalled in the side walls of said body and engaging said rod to move the same substantially vertically, and a cap inclosing the upper end of said body and arranged to maintain said crank pin in said body.

5. In a waste operating mechanism, a body, a guide member secured to said body and removable therefrom, a hooked rod slidably mounted within said guide member and projecting into said body, acrank pin journalled in the side walls of said body and engaging said rod to move the same substantially vertically, and a handle secured to said crank pin, said handle having a pair of arms extending around said body and engaging the terminating ends of said crank pin.

6. In a waste operating mechanism, a body, means for securing said body to a fixture, a guide removably secured to said body, a hooked rod slidingly mounted in said guide, a crank pin journalled in said body and engaging said hooked rod to move the same substantially Vertically and a handle for actuating said crank pin, said body sesignatures.
